Macroeconomics must take radical uncertainty into account, if it aims at contributing to the solution of serious real-world problems such as climate change. Allowing for radical uncertainty must happen at two levels: the level of modeling and the level of the scientific discipline. I argue that...

Participants in student loan programs must repay loans in full regardless of whether they complete college. But many students who take out a loan do not earn a degree (the dropout rate among college students is between 33 to 50 percent). The authors examine whether insurance against...

This paper studies general health insurance markets. It proposes an ex post risk adjustment scheme that discourages risk selection and promotes efficient competition. Under the proposed risk adjustment scheme, the regulator engages in transfers that are conditional on the ex post profits of...

The extant literature has used measurements of CEO risk-taking incentives which do not include the effects of termination provisions such as severance agreements. This paper provides a general form model that allows for the valuation and computation of CEO compensation structures including...

While most college graduates eventually find jobs that match their qualifications, the possibility of long spells of unemployment and/or underemployment—combined with ensuing difficulties in repaying student loans—may limit and even dissuade productive investments in human capital....

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. Risk classification can be used to mitigate adverse selection and improve insurance...

In a repeated unobserved endowment economy in which agents negotiate long-term contracts with a financial intermediary, we study the implications of the interaction between incentive compatibility and participation constraints for risk sharing. In particular, we assume that after a default...

The paper provides a framework for analysis of remuneration to agents whose task is to make well-informed decisions on behalf of a principal, with managers in large corporations as the most prominent example. The principal and agent initially bargain over the pay scheme to the latter. The...

This note considers the problem of a principal (she) who faces a privately informed agent (he) and only knows one moment of the distribution from which his types are drawn. Payoffs are non-linear in the allocation and the principal maximizes her worst-case expected profits. We recast the robust...

One of the standard predictions of the agency theory is that more incentives can be given to agents with lower risk aversion. In this paper, we show that this relationship may be absent or reversed when the technology is endogenous and projects with a higher efficiency are also riskier. Using a...
